Lupus is an autoimmune disease where the immune system mistakenly attacks the body's own tissues. It most commonly affects women, especially of certain ethnicities. Symptoms can vary significantly between individuals but include fatigue, rashes, and joint/muscle pain. The exact causes are unknown but genetics and environmental factors like smoking may play a role. Treatment involves a team of specialists aiming to prevent flares and organ damage through medications, lifestyle changes, and managing symptoms. While there is no cure currently, research continues to explore new treatment options like targeted drug delivery systems.
